iOS 10.1.1 front "retina" flash problem

So yesterday I updated my 64gb 6s plus from iOS 10.1 to 10.1.1 and after opening the camera app, recording for about two seconds with the rear one and switching to the front facing camera I got this message https://s11.postimg.org/bldise69f/IMG_1627.png which freaked me out a little and made me laugh at the same time because while it's being displayed I could still use the front flash. I let the iPhone sit for a while and tried doing the same thing after restarting it. Cellular data was off, multitasking bar was cleared and the phone was cold to the touch. And... I wouldn't have posted this if the issue was gone. Does any of You came across this or is it just me? Cheers.
